Is 20 cigs a day honestly the average nowadays?? Mind blowing and sad.
My mum who was an addicted smoker since she was 10 years of age and went through maybe 5 to 10 cigs a day.
it's been the average for a long time. it's due to nicotine's pharmacological effects. its half life is roughly 1~2 hours. so a smoker on average will feel the compulsion to smoke an hour or so after the last cigarette. since most people are awake somewhere 16 hours a day, that's about ~16 cigarettes a day.
your mom's smoking habits were definitely atypical
